Hilary Duff and husband Mike Comrie announced their split over a month ago, but it seems like they are still the best of friends.

Duff and Comrie, who were married for three years and have a son together, Luca, are spending Valentine's Day together. The "modern family," as Duff refers to it in her hashtag, is on vacation together in a sunny beachside location. Duff, 26, posted photos from the exotic locale to Instagram:

And tweeted to her over four million followers:

Hope everyone's heart feels full and content today. Whether it's with your love or just yourself! Smile ❤️
